Dealer wants how much? Check my math

[Hatche90]

24 AT4X 3.0. Coming up on 8K miles and will need a first PAID oil change. Normally do myself but I thought I'd call the dealer to price out oil change, fuel filter, and tire rotation. Here's what I got back:

Oil Change $128
Tire rotation $50
Fuel Filter $185
Total $363 ouch

What I was able to cobble together from the interweb for parts
3.0 oil change kit with oil and filter (free shipping) $80 - AC Delco oil and filter
Fuel filter $30
Tire Rotation. I can do it myself but getting it up on all fours is a bitch
Total $110 + beer

I’d personally do it myself. You can probably knock out all 3 in 30mins to an hour. Remove oil filter, drain engine oil, remove fuel filter, replace fuel filter, rotate wheels while oil is still draining, then install engine oil plug, oil filter, and put in new oil. You can probably get the oil a bit cheaper if you go with a different brand that’s still Dexos approved. I get a 6 pack of Mobil1 engine oil from Costco for $43.50 and an oil filter from the auto parts store for $10-15. I also change out my oil every 5k miles, so I’m not concerned about running oil that’ll “last” 10,000 miles before it’s next oil change

I replaced mine (fuel) when it was down to about 35 %, had almost 28k miles. Never noticed any change in performance or mpg. Like above, manual says the truck will tell you when it needs changing.

That’s not a bad price for the oil change. 7qts of oil and 30 mins of labor at ~$100/hr. Doing it myself, I'm paying at least $12/qt for a Dexos D approved oil (I like Mobile 1 ESP X2), plus ~$12 for the PF66 oil filter. That’s almost a $100 right there. $30 bucks for someone else to get oil on them sounds good to me.

Tire rotation…. I mean…. $50 is a bit steep. See if you can find a coupon on their website for a free rotation.

You don’t need to change the fuel filter at 8k miles. Unless you’re seeing a noticeable drop in fuel economy, rough running, etc., wait until the truck says you have 30% or less of life left in it. The Duramax engine supplement owners manual says fuel filter every 30k miles or two years. It’s not hard to do at all except it requires something like a 38mm socket. Make sure you get new o-rings with your fuel filter though.
